KEROSENR SIGNALING LAMP.

Application filed June 17,

My invention relates particularly vI to a lamp adapted to be used in a lantern for j ceptacle and "fill it with absorbent cotton or the like from the bot-tom to a point approximately. oneshalf of an inch from the top of the pot, leaving a comparatively shallow chamber 'to. receive the lower end of v the usual adjustable wick, and for expansion as explained in the following specification.

The drawings show three modifications of my invention.

Figure 1 is a vertical sectional view showing the preferred form of the invention with the tube secured to the burner.

Figure 2 is a side view alfi partial section showing a separable tube.

Figure 3 is a Vertical section and side ele vation of a construction in which the tube is secured to the pot.

The pot 5 may be of any suitable construction having a top 6 with a screw threaded mouth 7.

The burner 8 in this form has a flat wick tube 9 with an adjusting member 10 and a screw threaded portion 11 adapted to screw into the mouth 7 of the pot in the usual manner. The wick 12 may be of the usual type of cotton wick sufficiently long to permit of burning and trimming from time to time. In this form I secure a tube 13 to the bottom of the burner and long enough to. reach nearly but not quite to the bottom of the pot. Inside of this tube 13 I provide a filling wick 14 of absorbent cotton or the like sufficient to reach the bottom of the pot.

The lowerportion of the adjustable-wick 12 rests against the top of the stationary wick 14 so that as long as there is any oil in the pot it will be absorbed up through the wicks 14 and 12. Preferably I provide means such as crosspin 15 within thetube 13 to limit the insertion of the wick 14 into the tube up to the level of the oil of a properly filled 1924. Serial No. 720,506.

pot and thus insure that a chamber 16 is left between the bottom of the burner and the top of the wick 14. This chamber 16 is necessary to provide forstorage of surplus adjustable wick 12 and also provide space for expansion of the little oil that may, by capillaryattraction, collect on the upper surface of. the'filling wick 14. This occurs whenthe'lamp is not burning and is standing in a warm placc'or in the suns rays. lVhen'in this condition, the lamp being lit and producing suddenly additional excess heat will cause expansion of this oil which must be. cared for untilconsumed, to prevent overflow to the burner. The wick 14 acts as check to the -o1lso as to prevent the voil running out if the lamp be tipped over.

It also insures the steady provision of oil .near the top of thefount for absorption by the adjustable wick even when the oil in the tween the bulk of oil in pot 5 and burner 8 with wick 12 preventing flushing of the flame, by violent signaling which otherwise lamp is swung.

In the form shown in Figure 2 the tube 20 for containing the soft cotton or other ab- 'fount is quite'low.- It alsointervenes besorbent 21 is formed separate and adapted to be readily attached to the burner 22; for

instance, by means of a screwthrea-deed extension or collar 23 on the bottom of the burner. By providing a screw thread 24 of the proper length the extent to which the tube 20 may be screwed into the extension 23 may be limited so as to insure the provision of the storage and expansion chamber 25. V v

In the form shown in Figure 3, the tube 30 is secured to the top 31 of the pot and filled with absorbent material 32 to the desired height. provided" with an extension sleeve '34: adapted to fit into the upper end of the tube 30 and also adapted to press the cotton 32 down so as to leave a proper storage and expansion chamberv 35 beneath the burner.

'In this form of. construction, to facilitate filling with oil I may provide a fillingopening and cap 36 which of course is unnecessary in the form shown in Figure 1, where the removal of the burner and tube leaves the mouth open for filling.

A burner 33 in this case is I also prefer to )rovide a gage to indicate the maximum height to which the pot should be filled. This may be in the form of a simple strip 37 secured to the under side of the top (3 close to the mouth of the pot as shown in Fig. l, or it may be secured near the filling opening 36 as shown at 38 in Fig. 3.

All the three forms of construction herein shown and described will be seen to be simple and easy to make according to the highest standards of manufacture. They have also been found to be absolutely safe in use. that is, they will not leak and they will not go out when used as railway signaling lanterns are commonly used.

I claim:

1. A kerosene signaling lamp comprising a pot, a burner detachably secured in said pot, means for adjusting a wick in said burner, a tube attached to and extending from the bottom of said burner to approximately the bottom of said pot, and absorbent packing filling said tube from the bottom thereof up to a point below the bottom of said burner and approximately at the maximum level oi the oil in the pot so as to leave an expansion and storage chamber and a depth gage arranged inside said pot at approximately the level of the top of the absorbent packing in the tube.

2. A kerosene signaling lamp comprising a pot, a burner detaehably secured in said pot, a wick carried thereby, means for adjusting said wick in said burner, a tube carried by said burner and depending therefrom, and stationary absorbent. fibre filling in said tube spaced apart from said burner to accommodate a sullicient length of wick and extending to the bottom of said pot and a depth gage arranged inside said pot at approximately the level of the top of the absorbent packing in the tube.

3. A kerosene lamp con'lprising a pot having a top, a burner and tube carried thereby having an expansion and storage chamber on the level of the upper part of the pot, an absorbent packing in the lower part oi said tube and an adjustable wick in said burner having its lower portion extending through said chamber into contact with said absorbent packing and a depth gage arranged inside said pot at approximately the level of the top of the absorbent packing in the tube.

4. A kerosene lamp comprising a pot, a burner having an adjustable wick, a tube depending from said burner, absorbent material filling the lower end of said tube and a cross rod in said tube for preventing said absorbent material from coming in contact with said burner.
